There is this important element in the pursuit of cavalry by cavalry. The pursued cannot halt without delivering himself up to the pursuer. The pursuer can always see the pursued. If the latter halts and starts to face about the pursuer can fall upon him before he is faced, and take him by surprise. But the pursued does not know how many are pursuing him. If he alone halts two pursuers may rush on him, for they see ahead of them and they naturally attack whoever tries to face about. For with the about face danger again confronts them. The pursuit is often instigated by the fear that the enemy will turn. The material fact that once in flight all together cannot turn again without risking being surprised and overthrown, makes the flight continuous. Even the bravest flee, until sufficient distance between them and the enemy, or some other circumstances such as cover or supporting troops, permits of a rally and a return to the offensive. In this case the pursuit may turn into flight in its turn. Cavalry is insistent on attacking on an equal front. Because, if with a broader front, the enemy gives way before it, his wings may attack it and make it the pursued instead of the pursuer. The moral effect of resolution is so great that cavalry, breaking and pursuing a more numerous cavalry, is never pursued by the enemy wings. However the idea that one may be taken in rear by forces whom one has left on the flanks in a position to do so, has such an effect that the resolution necessary for an attack under these circumstances is rare. Why is it that Colonel A---- does not want a depth formation for cavalry, he who believes in pressure of the rear ranks on the first? It is because at heart he is convinced that only the first rank can act in a cavalry charge, and that this rank can receive no impression, no speeding up, from those behind it. There is debate as to the advantage of one or two ranks for the cavalry. This again is a matter of morale. Leave liberty of choice, and under varying conditions of confidence and morale one or the other will be adopted. There are enough officers for either formation. It is characteristic of cavalry to advance further than infantry and consequently it exposes its flanks more. It then needs more reserves to cover its flanks and rear than does infantry. It needs reserves to protect and to support the pursuers who are almost always pursued when they return. With cavalry even more than infantry victory belongs to the last reserves held intact. The one with the reserves is always the one who can take the offensive. Tie to that, and no one can stand before you. With room to maneuver cavalry rallies quickly. In deep columns it cannot.
